You cannot. You will have to use a player that have volume control. The
alsaplayer can be run as a daemon and you can control it from a terminal. You
can run several alsaplayer daemon if you want to and control them. For that to
work, you have to give them different names (man alsaplayer).

It's normal, alsa is a hardware driver, not a software volume control.

Another way is to run jack as sound server. It is several mixers for it. As
example, you can add as many volume control than needed with jackmixer and
connect them with every jack input or output (hardware or software) with
qjackctl.

Some jack users are using a rt-kernel, but you will not need it so long you are
not doing heayvy uses of software synths or audio filters.
